Just listened to both of them yesterday and I really liked the 804d's. The 805d's are definately going to need a good subwoofer whereas the 804d's sounded good all by themselves, though a subwoofer wouldn't hurt them either. Also, I felt that even with a subwoofer the 805d's upper bass and lower midranges might still be lacking compared to the 804d's. The 805d's did sound very good for what they are but not nearly as satisfying or enjoyable as the 804d's. Also, cosmetically, I thought the 804d's looked better. I didn't care for the stands on the 805d's which also adds another $700 to the cost. By the time you add the stands and a subwoofer, you're close to the cost of the 804d's. All of this is of course just my opinion. I also listened to some Maggie's that were nice too and alot cheaper. If only they weren't so damn big! Good luck.
